Chicago, IL — Fog is expected to develop overnight across northeastern Illinois, with the densest fog likely near the Lake Michigan shoreline, prompting visibility concerns and commuter delays into Wednesday morning.
According to the National Weather Service Chicago, the fog may persist through early Wednesday, especially along the immediate lakefront, where northeast winds will trap moisture near the surface. Isolated pop-up showers are possible Wednesday afternoon, but Thursday brings a higher potential for severe thunderstorms, particularly in the late afternoon and evening hours.
Temperatures will remain warm through the end of the week, ranging from the low 70s to mid-80s, with humidity levels climbing. Breezy conditions on Thursday and Friday will elevate the risk of fire danger in central and southern Illinois.
Residents are advised to limit outdoor burning and remain alert for potential weather advisories. Wind gusts and dry vegetation could allow fires to spread rapidly.
By Saturday, conditions should ease, with calmer weather and temperatures returning to the low 70s.
Travelers should monitor local forecasts, allow extra time for morning commutes due to fog, and stay weather-aware through the week as conditions shift rapidly across the state.
